Abstract
Differing metallic electrodes having the same or differing thickness are formed at different locations on a support structure and/or on a single thickness film of piezoelectric material in order to form a multiple frequency resonator device having greatly separated acoustic resonance frequencies. A plurality of multiple frequency resonators can be combined to form a blank of frequency selective devices in order to handle the many different RF bands, at widely varying frequencies, that wireless communication technologies demand today.
